Hi Marshall, thanks for your reply. I think I have figured it out: I had
not realized the session object saves data under a per-component name
space, which prevented the serializer from finding the data saved by the
collection reader and deleting it.

I'll try an alternative strategy today and come back of I bump into any
other issues.

Thanks!
Jta
